, a specification.

disc variety.

The -present invention relates to vehicle wheels,.having reference particularly to an improved pneumatic cushion-wheel of the The invention has for an object4 the `pro-A f vision lof a wheel of thischaracter which is of such construction as toobviate liability of puncturing its pneumatic element.

A further object of the invention is to provide means for absorbing shock, between Y the wheel hub and its traction tire.,

Still further objects being the provision of an improved vehicle wheel which is simple in construction, durable, inexpensive and relatively light in weight, and which is capable of sustaining considerable lateral impact without liability of vserious Iinjury to its several elements.

In the attainment of these and other objects we employ an adaptable hub having a wheel fixed thereto, consisting of ajsubstantially concavo-convex metal disc havingI a peripheral flange constituting a rim, a peripherally split annular shoe mounted 'on said rim, a pneumatic tube within said shoe, a rtelly-band on the -outer periphery of'said shoe, andfmeans for anchoring said shoe to the Outer peripheryl ofsaid wheel rim and r to the'inner4 periphery of said telly-band, and guard-means laterally spaced from said shoe for coincidentally allowing of its lat eral expansion and guarding it against injury, and means for detachfably connecting the said elements, and other novel features hereinafter Ji'ully described and specifically set forth in the appended claims.

In the accompanying drawings forming A part of this specification,

Figure l is an outside view of a segment of my improved Wheel;

Figure 2 is ia cross sectional view taken on the line 2-2 of Figure 1; and

Figure 3 is `a cross sectional View of the ,shoe-element.

n the examplevof the invention illustrated by the drawings, 1, indicates a Vhub of adaptable standard variety and yhaving on its inner end a flange'2, mounted adjacentv to the outer end of the hub 1, and laterally spaced from the ange 2, by means of an annular member 3, is myimproved disc-wheel indicated in general by 4,* and which comprises a front wall 5, an inwardly "and obliquelydirected body-part `6and an annular flange 7, said wheel being held 1n place by means ofbolts 8 which are coin.- cidentally employed for securing a brakedrum9 and a hubcap 10.

M-oimted peripherally on the outer surface of the flange 7 ,by lmeans of rivetsv12, is Ia plurality of radially extending dovetailed tongues 11 which are longitudinally pierced for engaging fasteningbolts hereinafter described. f

The tongues 11 are adapted for interlocking engagement with dove-tailed grooves 1l formed on the inner periphery of the flexible shoe 13 which encloses the pneumatic elastic tube 15, said shoe beingv split at its inner periphery, whereby the tube Vmay be We. further provide an .annular outside guard-plate l22 which is laterally spaced'- trom the shoe 13, to allow for expansion thereof, and which bears at its outer edge part on the flange 20; and an annular inside guard-plate 23 which is also spaced from theshoe 13 and provided with an obliquely directed flange 24, which parallels thereon. l e

We also employ a demountabletire rim 25, and tire 26, and suitable clips 27 lthe plates 22, 23, telly-band 16, tire rim 25, and clips 27, being held in l'ixedrelation by means of cross bolts 28 which lextend through said element-s and through the tongues 17.

AS a further means 01 guarding .theshoe' the flange 21 of the telly-band 16 and bears ,l i

land stabilizing the structure, We employ ring-plates 29 which are respectively provided With a beaded edge part 30, Vconstituting an lannular groove for ,containing a suitable packing ring 31. These plates 29 are held in place by means of cross bolts 32 which extend there thro-ugh andlt'hitough the tongues 11. i

The ring-plates are respectively curved and laterally spaced from the shoe A13 to i allow for lateral expansion of saidshoe, and

y the ,packing rings v31 constitute efficient guard-plates and `the shoe yallowing the neclessaryl eXpansionand contraction, and admittiiig ofV shock being absorbed by said 533 pneumatic elementy Without liability of-having its components injured by puncture.

i Vhile We haveillustrated and described a Vfairexample'o-fgtheinvention, We donot Wish to be understood as confining ourselves to the ,speicic details of lmere .mechanical construction; and formation of the elements setv forth, as under the spirit of' ourvinvention, We beliefvethat ive are entitled to enr ploy such" variations of detailas may fall' ,Within the scope of the appended claims.
